    WAY 1 Using Phono (RCA) leads
    To remove clicking/poping noise when stereo mutes when aftermarket Head unit fitted.
    Depending on Bose upgrade you will have i believe 2 or 4 phono plugs depending on how many speakers are amped up.
    so you need to make up the same number of leads which are put inline with the new Head unit with phono(RCA) outputs.

    Tools requied

    soldering iron
    solder
    pair wire cutters
    electrical insulation tape
    pliers (with an elastic band on the handle to hold plugs so you dont get burnt)
    screened cable
    2 or 4x phono sockets
    2 or 4x phono plugs (i used angled to get stereo to go in further and to fit in capacitors)
    15uf ish capacitors in line pref

    It seems to work well in my A6 with all bose speakers amped and sub
    but due to bose EQ in amps you may need to reduce treable:)

    Way 2 using speaker outlets with a Speaker to Phono(rca) line level reducer from such companys as autoleads etc
